How can a natural stone or brick facade be protected against dirt and algae?

Facades made of natural stone or brick give buildings a distinctive and robust appearance, but they are often susceptible to dirt buildup and algae formation. This problem is especially common in damp and shaded environments, where dirt and algae can quickly accumulate. This is not only unsightly but can also lead to long-term structural problems if the facade is not properly maintained. Dirt and algae can penetrate deep into the pores of the stone or brick, making them difficult to remove and leaving the facade looking perpetually unkempt. Therefore, it is important to apply effective protection that makes the facade less prone to dirt and algae, ensuring that the surface stays cleaner for longer and is easier to maintain.

Lithofin Splash-Stop >W< makes facades less prone to dirt buildup and algae, keeping them cleaner for longer and easier to maintain.

Lithofin Splash-Stop >W< is a water-based impregnating agent specifically developed to protect facades made of natural stone, brick, and other mineral surfaces from dirt and algae. This product penetrates deep into the pores of the material, forming an invisible, hydrophobic layer that prevents moisture and, therefore, dirt and algae from penetrating the facade. As a result, dirt remains on the surface, where it can be easily removed. Lithofin Splash-Stop >W< does not alter the color or appearance of the facade, and it can be used both indoors and outdoors. It is easy to apply with a brush, roller, or sprayer, and it dries within 30 to 60 minutes. One liter is sufficient to treat 10 to 25 m², depending on the absorbency of the surface. By treating your facade with Lithofin Splash-Stop >W<, it stays cleaner and free from algae for longer, simplifying maintenance and extending the facade's lifespan.
